Cable trough unit

Cable trough unit is used for cable laying on single-track railway and two-ways track railway bridges. Work-pieces conform to standards GTSS 410111 (SHP-59-01).


On railway bridges cable is laid out with the use of inlying sheet-iron chute cable duct. Cable ducts are mounted on outboard supports; cable trough length  is not to exceed 2,0 m.

Cable trough typical size is 140 mm ×200 mm, sectional view:

  • 140×300 мм
  • 140×400 мм
  • 200×300 мм
  • 200×400 мм

There are following types of cable trough:

  • span/for operation in a span
  • end-capping/for below coastal area ground allocation
  • extended, for conductor joints

Use of cable trough provides: 

  • easy mounting on any type of bridge span (reinforced concrete or metal)
  • favourable location on the bridge
  • conductor joints – and reserve cable easy mounting
  • signal- and supply cable trapping
  • unauthorized people access guarding


Work-pieces conform to standards GTSS 410111 (SHP-59-01); needed for bridge span cross-walk providing (top road bridge and bottom-road bridge).The equipment is used on single-track railway and two-ways track railway bridges.

Usage pattern:

  • Unit cover plate provide access to cables; there are mountings with locking mechanism (for span and extended sections)

  • drain condensation holes

Support types:

  • Type 1 screw retainment to underside of bridge

  • Type 2 holdup screen and constructions above screw retainment

  • Type 3 cable anchorage to abutment pier

Supports may be fastened by welding operation, maximal step 1,5 m. Mounting hardware height control and above bridge overhanging length control of the unit is possible.

  • splitters may be used for  signal- and supply cable trapping

  • cable components unfit for pass-through it

  • cable trough base stand fibreglass elastic foundation protects the cable from accident-caused damage

  • corrosion-resistant coating

Important: the quantity of supports is counted off as 1 pcs per 1,5 m of the bridge length.
